> 中文摘要: 在开放动态的互联网环境下的云服务呈现出发散、动态演化、异构等特征,为了适应多样的应用需求以及持续变化的云环境,云需要以灵活、适应的方法来有效地管理和提供云服务.针对这一需求,提出了一种云服务自组织管理方法,该方法利用agent的环境感知和自主行为决策的能力,依据它的职责实现对云服务的自主管理,并通过agent间的交互以自组织的方式实现对服务资源的有效管理,进而适应云环境和应用需求的变化;提出了支持上述方法和机制的实现技术,包括云服务自组织管理的核心机制和实现框架、云服务汇聚和提供的运行机制及相关实现算法.利用支持语义Web服务发现匹配的公共测试数据设计并完成了两组验证实验,实验结果表明:所提出的方法可以在持续变化的云环境下有效地管理和提供云服务,进而满足动态多样化的应用需求.
Abstract:Cloud services in dynamic and open Internet environment are typically decentralized, evolving, and heterogeneous. To satisfy the dynamic application demands and to respond to the continuous changes of the cloud environment, cloud services need to be provided and managed in a flexible and adaptive way. Aiming to address the challenge, this paper proposes an approach for cloud services self-organizing management. It achieves the autonomous and flexible management of could services based on MAS that are context-aware and autonomous in behaviors. The agents governing the services interact with each other to implement self-organization in order to response to the continuous changes of cloud environment and application requirements. The paper presents the mechanisms and implementation techniques for the approach, including cloud service self-organization management mechanisms and implementation framework, cloud services aggregation and provision mechanisms and relevant core algorithms. Experiments based on public test data are performed, and the results show that the proposed approach can effectively provide and manage services under the evolving environments for various requirements of applications.
